Specification of l'letto rs Patent.

Patented lien. .53, l'll lltl Application filed September 10, 191s. Serial No. 325%,c12.

To all whom it may concern Be it known that l, @r'ro PnDnnsnN, a c1timen or the United fdtates, residing at Brooktion, the jaws will be closed and the pipe firmly gripped and held.

Another object is to provide a wrench or this character with a sliding and a pivbted jaw connected to cooperate to grip and re liably retain a pipe or other object without any adjustment being necessary, a manipula- 'tion of the handle ope 'ating to actuate these aws.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being unde stood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 represents a side elevation with parts broken out of the wrench constituting this invention with a pipe shown gripped between the jaws thereof, said pipe being in section.

Fig. 2 is a longitudinal detail section taken on the line 22 of Fig. 1,

Fig. 3 is a similar view taken on the line 3-3 of Fig. 1, and

Fig. 4: is a transverse section taken on the line t I of Fig. 1.

In the embodiment illustrated, a handle 1 is shown having an integral arm 2 extendin obliquely outward from one end thcreoi and which has the usual shape oi an alligator wrench jaw. This arm or jaw 2 is provided along the side edges of its inner face with laterally extending flanges 3. A sliding toothed member 5 has inturned flanges 6 on its side edges adapted to extend under the flanges 3 oi the arm 2 as is shown clearly in Fig. t, whereby the member 5 is held in sliding relation to said arm. The teeth at or this member are inclined outwardly as shown in Fig. 1 and are designed to rooperate with inwardly inclined teeth on a pivoted jaw 10.

ll recess 7 is tormed at the inner end or base of arm 2- on its inner face and a short arm 8 extends obliquely outward from the handle in a direction opposite to the arm 2 and is designed to support the pivoted jaw 1.0 and to o erate as a stop for limiting its outward movement. This arm 8 has an apertured lug 9 extending from its inner edge or taco, and onwhich jaw 10 is pivoted as shown at 11. tahoulders 12 are formed on either side 01 the lug 9 so that the rear curved edge 13 0t jaw 10 will abut thereagainst and limit the opening movement of said jaw.

The aw 10 has a substantially right angular finger extending from its pivoted end edgewise toward the arm 2, the end oil? said finger being curved to operate in the recess 7. This linger 1 1 is connected by a link 15 with the inner and of the sliding jaw 5 so that when said sliding jaw 5 reciprocatcs on arm 2 it will actuate the pivoted jaw 10, the inward movement or said sliding jaw causing the pivoted jaw to close and the outward movement thereof operating to open the pivoted jaw. It will thus be seen that when the sliding jaw member 5 is engaged with a pipe P or other object to be gripped, and the handle 1 moved toward the left, jaw 5 will move inwardly and thereby close jaw 10 into gripping engagement with the pipe, and the teeth of these cooperating jaws will securely hold the pipe relatively to the wrench.

From the above description it will be obvious that this wrench, while very cheap to manufacture, is strong and eflective in operation, and has few parts to get out of order or to be broken.

From the foregoing description, taken in connection with the accompanying drawings, the advantage or the construction and oi the method of operation will be readily apparent to those skilled in the art to which the invention appertains and while I have described the principle of operation or the invention together with the device which ll now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the claimed invention.

the scope oil? Having thus fully described my invention,

what I claim as new and desire to secure by Letters Patent, is

1. A wrench of the class described comprising a handle with a slidable and a pivoted jaw mounted thereon, a link connection between said jaws whereby the inward movementof the sliding jaw will operate to close the pivoted jaw and its outward movement to open it.

2.'A wrench of the class described comprising ahandle with a slidable and a pivoted jaw mounted thereon, connecting the inner ends of said jaws whereby the movement of the sliding jaw will operate to actuate the pivoted aw.

3. A wrench of the class described comprising a handle with a rigid arm extending obliquely from one end, a toothed jaw mounted to slide on the inner face of said fixed arm, a jaw pivoted at its inner end acent the base of said arm and having a finger extending'laterally from said pivot, and'a link'connecting the free end of said a link pivotally finger with the inner end of said sliding jaw.

at. A wrench of the class described comprising a handle with a rigid arm extending obliquely from one end with a recess at the base of its inner face, and a short arm extending obliquely in a direction opposite to said first mentioned arm, a toothed jaw mounted to slide on the inner face of said first-mentioned arm, a jaw pivoted at its inner end on said short arm with a finger extending laterally from said pivot in edgewise direction from said jaw, a link connecting the free end of said finger with the inner end of said sliding jaw, said short arm having means for limiting the opening movement of the pivoted jaw.

In testimony whereof I alfix my signature in presence of two witnesses.
